www.holtec.com l Page 5 HI-STAR 100 License Expiration Date: 10/4/2019 Timely Renewal Date: 9/4/2019 3 Approved Amendments, 1 in process MPC inside sealed overpack www.holtec.com l Page 6 Renewal Application Following guidance in NUREG
-1927 Rev 1 and NEI 03 Have also reviewed the MAPS report, although significant portions of the application were developed prior to issuance of draft NUREG Apply for 40 year extension of the existing license Application requires Aging Management Programs (AMPs) or Time-limited Aging Analyses (TLAAs)

www.holtec.com l Page 8 HI-STAR 100 Scoping Process
- Following NUREG
-1927 2 Scoping Questions -Classified as Important to Safety (ITS)?
-Classified as Not Important to Safety (NITS), but failure could prevent fulfillment of an ITS function?
Applied to major SSCs in HI
-STAR 100 System
www.holtec.com l Page 9 HI-STAR 100 Scoping Structure, System, or Component (SSC) Scoping Results In-Scope SSC Criterion 1Note 1 Criterion 2Note 2 MPC Yes N/A Yes HI-STAR 100 Overpack Yes N/A Yes Fuel Assembly Note 3 Yes N/A Yes ISFSI Pad No Yes Yes ISFSI Security Equipment No No No Fuel Transfer and Auxiliary Equipment No No No Notes: 1.SSC is ITS 2.SSC is NITS but failure could prevent ITS function from being fulfilled 3.Fuel pellets not included
www.holtec.com l Page 10 HI-STAR 100 Scoping Application breaks down into sub
-components and intended function Further evaluation only based on those that have intended safety function
-Safety function based on: confinement, criticality control, heat transfer, structural integrity, shielding, and retrievability
-Example: MPC drain tube, not considered for aging as it does not serve those functions during extended storage period Tables in application go into detail on materials, environment, etc
www.holtec.com l Page 11 HI-STAR 100 Inspections Focus of Baseline / AMP inspections
-No canister inspection
- inert environment
-Exterior inspection for generalized corrosion / coating damage
-Seal inspection
-Pad inspection
- ACI-349 - Three tier inspection No specific pre
-submittal inspection
-No plans to open sealed overpacks
-During initial storage period, annual exterior inspection showed no OE that would change renewal inspections
www.holtec.com l Page 12 HI-STAR 100 Overpack Exterior AMP Continuation of existing FSAR requirements
-Exterior visual inspection
-Shielding effectiveness test All corrective actions / confirmation are referred to the site's QA program
www.holtec.com l Page 13 HI-STAR 100 ISFSI Pad AMP Annual inspection of concrete pad Following Standard in ACI
-349 - quantitative three
-tier -Acceptance without further evaluation
- free of significant deficiencies
-Acceptance after review
- some degradation, but can maintain design basis function
-Acceptance requiring further evaluation
- degradation, could prevent design basis function from being maintained Corrective actions from tier 2 and 3 are referred to the site's QA program
www.holtec.com l Page 14 Other Items MPC -Inside inert gas environment
-No aging mechanisms identified that require management Fuel Assemblies
-HI-STAR 100 does not have high burnup fuel
-No credible aging mechanisms Radiation Exposure
-Impact on materials
-Not a TLAA (not part of initial license basis), analysis still needed TLAAs - MPC fatigue evaluation (lifting)
www.holtec.com l Page 15 HI-STAR 100 Changes Amendments Amendment 1
- Approved contents updates Amendment 2
- Pad design changes Amendment 3
- Addition of MPC
-32 (in process)
Amendment changes don't appear to have significant changes to how aging effects will be managed
www.holtec.com l Page 16 HI-STAR 100 Changes
- 72.48s / Other CoC Renewal application process will evaluate changes made under 72.48 related to HI
-STAR 100 Any changes that impact aging management will be identified
